A1A-D25C Load Cell Digital Amplifier
ANYLOAD A1A-D25C strain gage amplifiers provide load cell and transducer signal conditioning. The A1A-D25C series strain gage amplifiers are DC-powered amplifiers that can drive 1 load cell connected directly. They can also drive several load cells up to 4 x 350Ω load cells or 8 X 700Ω load cells through a junction box. Housed in an aluminum casting enclosure. The A1A-D25 digitizer module includes both RS232 and RS485 communication interfaces with ModBus protocol.
- One input port, can connect directly to 1 x 350 Ω load cell, or max 4 x 350 Ω (or higher resistance) load cells through a junction box
- 24-bit A/D Converter, high speed processor
- Internal digital filter and strong anti-interference ability
- Contains ability for 9 point linear calibration
- Applied to all kinds of strain gauge bridge-type load cell, such as, tension, compression, torque and so on.
